It just means that lactose intolerance is now recognised and accommodated. The body produces less of the enzyme (lactase) needed to break down lactose as we age, with the result that it ferments in the gut, producing gas. Undigested lactose reaches the outlet as a liquid. I'd rather be thought strange than be farting and squirting out cow nipple juice.
